Question

13. An airplane travels at a constant speed of 800 kilometers per hour (km/h).

Approximately how long will it take the airplane to travel 200 kilometers?

Answer 1

The time taken for the airplane to cover the distance is 15 minutes.

Step-by-step explanation:

Given;

velocity of airplane, u = 800 km/h

distance traveled by the airplane, s = 200 km

The time of this motion is given by;

s = ut + ¹/₂at²

at constant velocity, acceleration, a = 0

s = ut

t = s / u

t = (200 km) / (800 km/h)

t = 0.25 hour = 15 mins

Therefore, the time taken for the airplane to cover the distance is 15 minutes.
